although pure drinking water is brought to users, pain points of the users also exist. For example, most water purifiers need to stop water in a user control mode, and stop the water when the water is full, so that a user needs to keep around the water purifier when receiving water, and if the user leaves the water purifier in a temporary situation and forgets to press a stop key, the water overflows from a water cup, and waste and unnecessary troubles are caused. Some water purifiers can achieve quantitative water intake, that is, users can select water intake capacity (such as 150ML, 300ML, 500ML and the like) by themselves, and when the selected capacity is taken, water is automatically cut off. However, although the quantitative water intake technology can realize automatic water cut-off, the user cannot accurately select the flowing water capacity due to various capacity specifications of the user cup, and the phenomenon that water is cut off or water overflows from the cup when the water in the cup is not full easily occurs.
Therefore, the problem that the injection of the object into the container is stopped immediately when the container is full of the object cannot be realized by the throwing device in the related art is solved.

In this embodiment, after receiving the first distance and the second distance, the main control module may determine a first height of the first detection module from the target area, and determine a second height of the target object carried in the target container according to the first height, the first distance, and the target rotation angle. And determining the third height of the target container according to the second distance, and controlling the throwing device to throw the target object by comparing the second height and the third height.
In the above embodiment, when determining the second height, a first height of the first detection module from the target area may be determined first, then a first distance of the target object carried in the target container from the first detection module is determined by the first detection module, and the second height is determined according to the first height, the first distance, and the target rotation angle. The first height may be a predetermined height, that is, when the first detection module is installed, a vertical height of the first detection module from the target area may be determined, and the vertical height is determined as the first height. Of course, the first height may also be determined by the first detection module, for example, first adjusting the measurement angle of the first detection module to be opposite to the target area, controlling the first detection module to emit the ultrasonic wave and receive the reflected ultrasonic wave, and determining the first height according to the time difference between the emission time and the reception time and the wave speed of the ultrasonic wave.

In an exemplary embodiment, the main control module determines the second height of the target object carried in the target container based on the first distance, the first height and the target rotation angle by: determining a deviation angle of the detection direction of the first detection module from a vertical direction based on the target rotation angle; determining a product of the first distance and a cosine of the deflection angle; determining a difference of the first height and the product as the second height. In this embodiment, referring to fig. 6, the second height diagram is determined, and as shown in fig. 6, the ultrasonic module 2 starts to continuously transmit ultrasonic signals to detect the distance r (corresponding to the first distance) from the water surface and transmits the data to the main control board in real time. The calculation of the water level height (second height) h2, i.e. h2 ═ b-r × cos α, is carried out in the main control panel. Wherein b is the distance (namely the first height) between the ultrasonic module 2 and the table top for placing the water cup and is a fixed value; r is the distance (i.e. the first distance) from the water surface detected by the ultrasonic module 2; and alpha is the angle of the first detection module from the vertical middle line.
In an exemplary embodiment, the master control module determines the third height of the target container based on the second distance by: determining a relationship between the second distance and a predetermined threshold when the second detection module is at an initial position; if the relationship indicates that the second distance is less than a predetermined threshold, adjusting the height of the second detection module, and determining, by the second detection module, a third distance of the target container from the second detection module when the second detection module is at the current height, and if the third distance is greater than the predetermined threshold, determining the current height as the third height of the target container; adjusting the height of the second detection module if the relationship indicates that the second distance is greater than the predetermined threshold, and determining, by the second detection module, a fourth distance of the target container from the second detection module when the second detection module is at the current height, and determining, if the fourth distance is less than the predetermined threshold, the current height as the third height of the target container. In this embodiment, the initial position may be a position of a plane where the bottom of the target container is located, or may be a position of a predetermined height from the plane where the target area is located. When the initial position is the position of the plane in which the bottom of the target container is located, the second distance detected by the second detection module may be determined first. When the second distance is less than the predetermined threshold, the target container is considered to have been placed in the target area at that time. Therefore, the height of the second detection module can be adjusted, that is, the second detection module is controlled to move upwards, and the third distance is detected by the second detection module. And when the third distance is greater than the predetermined threshold value, determining the height of the second detection module at the moment as a third height.
In the above embodiment, when the height of the second detection module is adjusted, the second detection module may be controlled to move upward by a first fixed distance, a third distance from the target container to the second detection module when the height of the second detection module from the target area is the first fixed distance is determined by the second detection module, when the third distance is smaller than a predetermined threshold, the second detection module is controlled to move upward by the second fixed distance and detect the third distance by the second detection module, and when the third distance is larger than the predetermined threshold, the current height is determined as the third height of the target container. For example, the second detection module may be controlled to move upward from the bottom of the target container at a constant speed, first move upward by 8cm (i.e., a first fixed distance, which is only an exemplary illustration, and the present invention is not limited thereto), and the first fixed distance may be determined by the type of the target container, for example, the height of the cup is generally higher than 8cm, so the first fixed distance may be determined to be 8cm, and then the second detection module transmits a signal every time the second detection module moves upward by 1cm (i.e., a second fixed distance), and calculates a third distance according to the received reflected ultrasonic signal (from transmitting the ultrasonic signal to receiving the ultrasonic signal, the second detection module may stop waiting for 50 ms). And comparing the third distance with a preset threshold, controlling the second detection module to move upwards by 1cm when the third distance is less than or equal to the preset threshold, and detecting the third distance, wherein the preset threshold is 10 cm. Until the third distance is greater than the predetermined threshold, calculating and storing a height h1 of the target container, h1 ═ x + ny, where x is the first fixed distance, y is the second fixed distance, and n is the number of times the second detection module is controlled to move upward by the second fixed distance. For example, h1 is 8cm + n 1cm, where n is the number of times the second detection module is controlled to move up 1 cm.
In the above embodiment, after the second detection module moves upward from the bottom by the first fixed distance, the second detection module measures the third distance, and when the third distance is greater than the predetermined threshold, the second detection module may be controlled to move downward by the second fixed distance and move once to detect the third distance, until the third distance is less than the predetermined threshold, the current distance is determined as the third height.
In the above embodiment, when the initial position is a position at a predetermined height from the plane where the target area is located, the second distance may be greater than a predetermined threshold, when the second distance is greater than the predetermined threshold, the second detection module may be controlled to move downward and move once to detect the fourth distance, and when the fourth distance is less than the predetermined threshold, the current distance is determined as the third height.
In an exemplary embodiment, the main control module controls the delivering device to inject the target object into the target container based on the second height and the third height by: determining a product of the third height and a target constant, wherein the target constant is a positive number less than 1; and controlling the throwing device to stop injecting the target object into the target container under the condition that the second height is greater than or equal to the product. In this embodiment, after the third height of the target container is determined, a product of the third height and the target constant may be determined, and when the second height of the target object carried in the target container is greater than or equal to the product, the throwing device is controlled to stop injecting the target object into the target container. The target constant may be self-defined, for example, 0.9 (the value is only an exemplary illustration, and may also be 0.8, 0.95, and the like, which is not limited by the present invention). And when the second height is smaller than the product, controlling the releasing device to continuously release the target object until the second height is larger than or equal to the product.
In the above embodiment, a difference between the second height and the third height may also be determined in real time, and when the difference between the second height and the third height is smaller than a preset difference, the delivering device is controlled to stop delivering the target object.

The first height may be a predetermined height, that is, when the first detection module is installed, a vertical height of the first detection module from the target area may be determined, and the vertical height is determined as the first height. Of course, the first height may also be determined by the first detection module, for example, first adjusting the measurement angle of the first detection module to be opposite to the target area, controlling the first detection module to emit the ultrasonic wave and receive the reflected ultrasonic wave, and determining the first height according to the time difference between the emission time and the reception time and the wave speed of the ultrasonic wave. The first distance can also be measured by the first detection module, the first detection module is controlled to send out ultrasonic waves and receive reflected ultrasonic waves, and the first distance is determined according to the time difference between the sending time and the receiving time and the wave speed of the ultrasonic waves.
In an exemplary embodiment, determining a second height of the target object carried in the target container based on the first distance, the first height, and the target angle of rotation comprises: determining a deviation angle of the detection direction of the first detection module from a vertical direction based on the target rotation angle; determining a product of the first distance and a cosine of the deflection angle; determining a difference of the first distance and the product as the second distance. In this embodiment, referring to fig. 6, the second height diagram is determined, and as shown in fig. 6, the ultrasonic module 2 starts to continuously transmit ultrasonic signals to detect the distance r (corresponding to the first distance) from the water surface and transmits the data to the main control board in real time. The calculation of the water level height (second height) h2, i.e. h2 ═ b-r × cos α, is carried out in the main control panel. Wherein b is the distance (namely the first height) between the ultrasonic module 2 and the table top for placing the water cup and is a fixed value; r is the distance (i.e. the first distance) from the water surface detected by the ultrasonic module 2; and alpha is the angle of the first detection module from the vertical middle line.
In one exemplary embodiment, determining the third height of the target container based on the second distance comprises: determining a relationship between the second distance and a predetermined threshold when the second detection module is at an initial position; if the relationship indicates that the second distance is less than a predetermined threshold, adjusting the height of the second detection module, and determining, by the second detection module, a third distance of the target container from the second detection module when the second detection module is at the current height, and if the third distance is greater than the predetermined threshold, determining the current height as the third height of the target container; adjusting the height of the second detection module if the relationship indicates that the second distance is greater than the predetermined threshold, and determining, by the second detection module, a fourth distance of the target container from the second detection module when the second detection module is at the current height, and determining, if the fourth distance is less than the predetermined threshold, the current height as the third height of the target container. In this embodiment, the initial position may be a position of a plane where the bottom of the target container is located, or may be a position of a predetermined height from the plane where the target area is located. When the initial position is the position of the plane in which the bottom of the target container is located, the second distance detected by the second detection module may be determined first. When the second distance is less than the predetermined threshold, the target container is considered to have been placed in the target area at that time. Therefore, the height of the second detection module can be adjusted, that is, the second detection module is controlled to move upwards, and the third distance is detected by the second detection module. And when the third distance is greater than the predetermined threshold value, determining the height of the second detection module at the moment as a third height.

For example, the second detection module may be controlled to move upward from the bottom of the target container at a constant speed, first move upward by 8cm (i.e., a first fixed distance, which is only an exemplary illustration, and the present invention is not limited thereto), and the first fixed distance may be determined by the type of the target container, for example, the height of the cup is generally higher than 8cm, so the first fixed distance may be determined to be 8cm, and then the second detection module transmits a signal every time the second detection module moves upward by 1cm (i.e., a second fixed distance), and calculates a third distance according to the received reflected ultrasonic signal (from transmitting the ultrasonic signal to receiving the ultrasonic signal, the second detection module may stop waiting for 50 ms). And comparing the third distance with a preset threshold, controlling the second detection module to move upwards by 1cm when the third distance is less than or equal to the preset threshold, and detecting the third distance, wherein the preset threshold is 10 cm.

For example, h1 is 8cm + n 1cm, where n is the number of times the second detection module is controlled to move up 1 cm.
In the above embodiment, after the second detection module moves upward from the bottom by the first fixed distance, the second detection module measures the third distance, and when the third distance is greater than the predetermined threshold, the second detection module may be controlled to move downward by the second fixed distance and move once to detect the third distance, until the third distance is less than the predetermined threshold, the current distance is determined as the third height.
In the above embodiment, when the initial position is a position at a predetermined height from the plane where the target area is located, the second distance may be greater than a predetermined threshold, when the second distance is greater than the predetermined threshold, the second detection module may be controlled to move downward and move once to detect the fourth distance, and when the fourth distance is less than the predetermined threshold, the current distance is determined as the third height.

In this embodiment, after the third height of the target container is determined, a product of the third height and the target constant may be determined, and when the second height of the target object carried in the target container is greater than or equal to the product, the throwing device is controlled to stop injecting the target object into the target container. The target constant may be self-defined, for example, 0.9 (the value is only an exemplary illustration, and may also be 0.8, 0.95, and the like, which is not limited by the present invention). And when the second height is smaller than the product, controlling the releasing device to continuously release the target object until the second height is larger than or equal to the product.

The following describes the delivery method with reference to specific embodiments:
fig. 9 is a flowchart of a delivery method according to an embodiment of the present invention, and as shown in fig. 9, the method includes:
step S902, a user places a water cup;
step S904, the user presses the water intake switch;
step S906, the main control board triggers a camera (corresponding to the image acquisition module) to shoot a picture of the cup mouth of the water cup and sends the picture to the main control board (corresponding to the main control module);
step S908, the main control board performs image recognition, and outputs an angle α (corresponding to the target rotation angle) to be adjusted of the ultrasonic module 2 (corresponding to the first detection module);
step S910, the main control board drives the rotation motor (corresponding to the rotation sub-module) to adjust the corresponding angle α of the ultrasonic module 2;
step S912, the ultrasonic module 1 (corresponding to the second detection module) moves upward from the bottom of the cup at a constant speed, and firstly moves upward by 8cm (the height of the cup is larger than 8cm in general);
step S914, every time the ultrasonic module 1 moves up 1cm, transmitting 1 time of ultrasonic signal, calculating the distance D from the ultrasonic module to the cup wall according to the received reflected ultrasonic signal (corresponding to the third distance, from transmitting the ultrasonic signal to receiving the signal, the ultrasonic module needs to stop waiting for 50 ms);
step S916, comparing the distance D with a threshold value a (corresponding to the predetermined threshold value mentioned above), where a is assumed to be 10cm, repeating step S914 when D < ═ a, and moving the ultrasonic module 1 up by 1 cm; step S918 is executed when D > a;
step S918, when D > a, calculating and storing a cup height h1, h1 being 8cm + n × 1cm, where n refers to the number of times step e is performed;
step S920, the water purifier starts to inject water;
step S922, the ultrasonic module 2 starts to continuously transmit ultrasonic signals to detect the distance r from the ultrasonic module to the water surface and sends the data to the main control board in real time. The calculation of the water level height h2 is realized in the main control board, wherein h2 is b-r cos alpha, and b is the distance between the ultrasonic module 2 and the table top on which the water cup is placed and is a fixed value; r is the distance from the ultrasonic module 2 to the water surface; alpha is the angle of the ultrasonic module 2 deviating from the vertical central line;
step S924, comparing the water level height h2 with 0.9 × h1, executing step S922 when h2<0.9 × h1, and executing step S926 when h2> is 0.9 × h 1;
in step S926, the main control board notifies the water purifier to stop water injection.
In the embodiment, the ultrasonic sensor is adopted to be matched with the image recognition technology, so that the water level can be judged relatively accurately, and the function of stopping when the water is full is realized. The ultrasonic mode can realize the detection of the water level in the water cup, but because the position of the water cup placed by a user is not fixed, the ultrasonic wave can be blocked by the cup wall and cannot reach the water surface, and the water level cannot be detected correctly; the water level in the water cup is shot through the camera, the water level can be detected by using an image recognition algorithm, but the internal light of part of the cylindrical water cup is dark or the inner wall of the water cup reflects light, the water level cannot be distinguished by naked eyes of people in a shot picture, and the water level cannot be recognized by the image recognition algorithm. Therefore, the ultrasonic technology and the image recognition technology can be combined, the water level and the height of the water cup are detected by the ultrasonic technology, and the position of the cup rim of the water cup is detected by the image recognition technology, so that the ultrasonic module is guided to rotate by a proper angle, and the ultrasonic waves are aligned to the cup rim to be prevented from being shielded by the cup wall.
In the embodiment, the water level in the water cup when the water purifier is used can be accurately detected, and water injection can be automatically stopped when the water is full. The problem that the water in the cup is not full or overflows due to inaccurate judgment of the capacity of the cup by a user in the quantitative water taking method is solved, and the adopted ultrasonic technology does not need a complex algorithm, so that the requirement on hardware resources is not high, and the cost is greatly reduced.
